MCT Photoconductive detectors

The PCI-λopt (λopt – optimal wavelength in micrometers) feature IR photoconductive detector, optically immersed to high refractive index GaAs hyperhemispherical (standard) or hemispherical or any intermediate lens (as option) for different acceptance angle and saturation level.

Example of D* vs Wavelength λ for PC Series HgCdTe Detectors. Spectral Characteristics of individual detectors may vary from those shown on the chart.

MCT Photoconductive detectors

Uncooled detectors are typically provided in packages (BNC, TO39) without windows. The exception is the specialized PEM package. Due to magnetic circuit incorporated into the package, a window is supplied to protect against pollution. There are two versions of packages dedicated for PEM detectors: PEM with SMA connector and PEM with TO8 base which allows to integrate detector with VIGO preamplifier.
